2 Claims.

This invention relates to writing pens and is especially concerned with pens or. pen points having writing tips of a novel and improved character.

One of the primary objects of the invention is to produce a pen having a writing tip of materially improved wearing qualities.

A further object is involved in the formation of a pen tip so as to provide more uniform and smooth flow of ink to the writing surface and to avoid sticking of the pen, especially on the upstrokes.

As a still further object, the invention contemplates improving the wearing and writing qualities by increasing the thickness of metal present at the tip. In accordance with this invention, furthermore, this increased thickness is provided by utilizing a blank of novel character including tabs or wings adapted to be bent to a position in which they extend in planes generally at right angles to the plane of a writing surface when the pen is held in substantiallynormal position.

The present invention also has in view improving the flow of ink from the slit and/or pierced part of the nib to the writing tip itself so as to make possible the production of lines of much more uniform thickness.

Additional objects and advantages, as well as those referred to above, will appear more clearly after aconsideration of the following description making reference to the accompanying drawing, in which Figure 1 is a plan view, on a considerably enlarged scale, of a pen blank which I prefer to employ;

Figure 2 is a side elevational view of a pen formed from the blank of Figure 1, also on a materially enlarged scale;

Figure 3 is a bottom plan view of the pen shown in Figure 2; v

Figure 4 is an end elevational view; and

Figure 5 is a fragmentary sectional view taken substantially as indicated by the section line 5-5 on Figure 4.

In considering the following description of my improved pen, and the preferred method of manufacture, it should be borne in mind that the invention is particularly concerned with that type of pen or pen point which may be formed in its entirety from a stamped blank. Pens of this character are ordinarily employed in the more inexpensive fountain pens as well as in the common desk penholders.

As clearly seen in Figure 1, the blank, shown by way of illustration, includes apart 6 adapted to be formed or rounded into a supporting heel. The part I of increased width constitutes the main body of the pen, and a tapered nib portion 8 extends from part I to terminate in the writing 5 tip. Blanks of this general form are preferably stamped from sheet or strip metal and, in the preferred manner of fabrication, the point is pierced, as indicated at 9., at the base of the nib.

In accordance with the present invention, the 10 writing tip of the blank is formed with a pair of laterally extended wings or tabs l0 and, in the fabrication of my improved pen, I bend these tabs l0 downwardly to positions in which they are disposed in side by side relation, as shown at 15 Illa in Figures 2 to 5 inclusive. These tabs, when bent in the manner referred to, thus constitute a writing tip composed of a pair of tabsor wings formed from metal of the original blank and extended in planes generally at right angles to the 20 plane of a writing surface on which the pen is adapted to be used.

By reference to Figures 2 to 5 inclusive, it will also be seen that the heel part 6 of the blank has been rounded, as shown .at Go, and further that 25 the body of the pen has been similarly rounded (see reference numeral 1a) Additionally, in following the preferred manner of manufacture, the wings Hla are bent to the positions clearly shown in Figures 2 to 5, and after this bending operation, 30 the nib is slit, as shown for example at H, between the adjacent tabs Illa-Illa. Where a nib piercing is employed, the slit is extended upwardly through the nib to join the pierced opening, as clearly shown in Figure 3.

Before considering some of the advantages of the foregoing structure, it should also be observed that in view of the original rounded formation of the tabs ill in the blank, and the manner in whichv the tabs are preferably bent, the base or 40 upper sides of the tabs are somewhat spaced from each other, as clearly shown at ilib in Figure 3. This spacing is of progressively decreasing dimension transversely of the writing tip toward the extremity thereof and, as a result, a. some- 5 what tapered aperture, functioning as a local ink reservoir, is formed at a point closely adjacent to the portion of the pen which contacts with the writing surface during use.

By virtue of the formation and construction 50 described above, extremely smooth and uniform writing qualities or characteristics are afforded. Especial attention is also called to the fact that the improved writing tip is produced by the bending of the tabs originally formed in the blank through only about As a result, the metal at the writing tip is not noticeably weakened, and this, in turn, is important in increasing the life of the pen.

It will be seen, therefore, that the pen of this invention is formed, in its entirety, from the metal of a single blank, and further that the increased thickness of the writing tip, as well as the substantially unimpaired strength of the metal, result in the formation of a pen having materially increased life.

A further advantage flows from the formation and bending of the tabs or wings at the tip in such manner as to provide a wedge-shaped ink reservoir closely adjacent to the writing surface. This is important in facilitating the production of lines of uniform thickness or width, the wedgeshaped cavity apparently acting as a local reservoir which is constantly fed and maintained full from'the supply of ink carried on the nib, especially in the slit and also in the pierced opening in instances where such an opening is employed.

I claim:

1. The method of manufacturing a pen which includes forming a blank having wings or tabs at opposite sides of the writing tip, bending said wings or tabs downwardly approximately 90 at opposite sides of a central area lying substantially in the original plane of the blank, and thereafter slitting the tip portion of the pen intermediate said wings or tabs through said central area.

2. A pen having a writing tip comprising a central part lying'substantially in the original general plane of the nib and extending to the extremity of the tip and a pair of wings or tabs bent approximately 90 downwardly from opposite sides of said central part along lines or axes generally paralleling the major axis of the pen but offset therefrom, the tabs lying in approximate paralie'lism with edges thereof presented downwardly to constitute the writing surface, and said central part having a slit therein extended substantially along the major axis of the pen formed therein between the bent tabs, and said pen further being characterized by tip portions thereof at opposite sides of an undistorted and straight-edged slit which are in contact with each other, at least at the extremity of the tip.
